Currently, rule G204 warns you about every single use of the
functions syscall.Exec, os.exec.CommandContext and os.Exec.Command.
This can create false positives and it's not accurate because you can
use those functions with perfectly secure arguments like hardcoded
strings for example.
With this change, G204 will warn you in 3 cases when passing arguments
to a function which starts a new process the arguments:
1) are variables initialized by calling another function
2) are functions
3) are command-line arguments or environmental variables

The big#Int.Exp used to be vulnerable in older versions of Go, but in the
meantime has been fixed (https://github.com/golang/go/issues/15184).

I thought that an example where the user inputs a URL is more realistic.
Because if your operating system is already hacked then you are already screwed.

- Get rid of 'core' and move CLI to cmd/gas directory
- Migrate (most) tests to use Ginkgo and testutils framework
- GAS now expects package to reside in $GOPATH
- GAS now can resolve dependencies for better type checking (if package
on GOPATH)
- Simplified public API
